.SH "DESCRIPTION"
.sp
Guetzli is a JPEG encoder that aims for excellent compression density at high visual quality\&. Guetzli\-generated images are typically 20\-30% smaller than images of equivalent quality generated by libjpeg\&. Guetzli generates only sequential (nonprogressive) JPEGs due to faster decompression speeds they offer\&.
.SH "OPTIONS"
